Basic Engine Building DVD - Chapter 36: Piston to Valve Clearance

In this chapter of the "Pre-Assembly" section we show you a great technique to check the piston to valve clearance. This is a very important step to do before you continue on to the final assembly of your block. First you need to know the firing order of your particular engine. You perform the check on your #1 cylinder.
